Abstract
Procedimiento para la aglomeración de sustancias dificilmente solubles y susceptibles de hidrólisis, caracterizado porque el polvo de la sustancia difícilmente soluble junto con al menos un aglutinante pulverulento soluble en agua, es conducido en caída libre a través de una atmósfera de vapor de agua a temperaturas entre 85oC y 105oC, esencialmente sin empleo de fuerzas compactantes, con un tiempo de residencia en la zona de vapor de unos 0,5 a 10 segundos y, a continuación, se seca en otra caída libre, de manera que a partir de los puentes líquidos originados por la condensación en los sitios de contacto entre las partículas primarias, en los que se encuentra disuelto agente aglutinante, solo se originan pequeños puentes de materia sólida y un proceso de secado inmediatamente posterior en un lecho fluidizado integrado, se seca hasta un contenido en agua de menos del 1% en peso.Procedure for the agglomeration of substances that are hardly soluble and susceptible to hydrolysis, characterized in that the powder of the hardly soluble substance, together with at least one water-soluble powdery binder, is conducted in free fall through an atmosphere of water vapor at temperatures between 85oC and 105oC, essentially without the use of compacting forces, with a residence time in the steam zone of about 0.5 to 10 seconds, and then it dries in another free fall, so that from the liquid bridges caused by condensation at the contact sites between the primary particles, in which the binding agent is dissolved, only small bridges of solid matter originate and a drying process immediately afterwards in an integrated fluidized bed, dries to a content of water less than 1% by weight.
